My 2002 7.3 cranks but won't start. This started about two days ago. It has 240k miles with the original glow plugs. I replaced the GPR but still no start. When I try to start the engine, I get alot of white smoke. The fuel pump is operating ok. I checked the oil level and HPP oil and it is ok. The IPR was replaced last year. Could the glow plugs and or the glow plug wire harness need replacing? I also replaced the CPS with no luck. What else would cause a no start situation? Thanks for any help.

Does it start if u plug the block heater in for 3-4 hours? Mine would only start when plugged in... I had 300k miles on it and had it diagnosed and over half of my injectors were bad.. I threw in some new swamps injectors in and problem fixed.. Paying $60 for the professional diagnosis was mine well spent instead of the replace and pray mentality... Although in hindsight I would have just bought the autoengenuity advanced ford bundle and diagnosed it myself..
